Upon death they drop one Moon Moth Wings. They can also be caught with a Bug Net, they can be planted to produce a Lune Tree sapling, and are the only method of replanting Lune Trees. When flying they emit enough light to prevent Charlie from attacking.

Unlike Butterflies, Moon Moths will starve outside of the inventory after approximately 4 minutes. Moon Moth inside the player's inventory will starve in 2 days unless fed. They can be fed with any Vegetable.
